CTS Turbo is excited to announce the release of the B9 Audi S4/S5 3.0T TFSI charge pipe upgrade kit. Factory pipe that connects intercooler to the throttle body is made of brittle plastic. It’s wise to replace it with an all-aluminum high flowing CTS Turbo charge pipe.

Our 2.5″ charge pipe kit will increase flow and improve the reliability of your B9 Audi S4/S5. You’ll notice an increase in throttle response and a decrease in turbo lag.

Two water/methanol bungs provide an easy way to install injection nozzles.

DESCRIPTION

CTS Turbo B9 S4/S5 3.0T (EA839) high flow cat is made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts – unleash your B9 S4/S5 3.0T potential!

Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from cast T304 stainless steel, hand TIG welded and back-purged to ensure years of reliable performance.

In addition to unleashing the power and performance of your 3.0T, the CTS B9 S4/S5 3.0T EA839 high flow cat will make your vehicle sound like an S-car really should. When installed with factory exhaust it produces a sporty growl with much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “braappp!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.
